you're talking about different things. u-boot is not a boot rom. the actual bootrom is a maskrom on the a64. the maskrom looks to spi/mmc for spl and u-boot. notably neither spl nor u-boot are xip in this case. spi/mmc are both easily overwritten from within u-boot (or any os loaded later) u-boot is not a boot rom. it is a bootloader.
